Yes I to can confirm that the usb bootable installers do show up in start up disk.

Hi Mark, I have not experienced what you are stating. In all previous version of the MacOS bootable installer on a USB stick that I have created, it was visible through the Startup Disk. I just tested my High Sierra USB installer and it was visible in the Startup Disk pane as well. I'm certainly not disputing that you've had that experience, but it is not the morn. Later...

The last time I checked, the only way I could see the bootable stick was via the Option key-press at startup. I have not yet made a bootable High Sierra stick so cannot confirm this but such was definitely the case in the previous OS.

Hi! I have created a bootable usb stick with Hi sierra as i have to do a clean install. The problem is that its not in the startdisk selection when i go to system prefs and start disk. I think i have made a mistake by formatting it to Mac os extended journal. I am not sure if this matters or not. Is there a way of checking wheather the downloaded installer may be corrupt or something else may have gone south? How big should the installer package be when its downloaded. Mine is 5 gb.
